A method for creating and accessing a graphical user interface in the overscan area outside the area of the display normally utilized by the common operating systems. This normal display area is generally known as the desktop. The desktop serves as a graphical user interface to the operating system. The desktop displays images representing files, documents and applications available to the user. The desktop is restricted in the common environments to a predetermined set of resolutions (e.g., 640.times.480, 800.times.600, 1024.times.768) as defined by VGA and SVGA standards. Displayable borders outside this area are the overscan area.
